19 Best B2B Data Providers and Vendors of 2025

So, how do you find the ones actually worth your time and money?

I did the heavy lifting and found the 19 best B2B data providers who actually deliver reliable, up-to-date data.

But what criteria did I use?

How did I choose the best B2B data providers and vendors?

I started by digging into communities and social media to see what real users want and recommend.

The problems

That’s when I spotted the pain points everyone’s complaining about:

1. Accuracy
2. Coverage
3. Scalability
4. Pricing

Next, I checked out the top-ranked Google pages to find providers claiming to solve these issues.

Spoiler: most of those listicles are total snoozefests. All you get is generic fluff. No testing. No user feedback.

Just a boring copy-paste of marketing copy from B2B data vendors’ websites.

So, I decided to get my hands dirty.

I made a big list of every B2B data provider I could find online and put them through a checklist built around those pain points and recommendations.

The criteria

I needed a checklist that actually means something. So, I boiled it down to 5 key factors to judge every B2B data provider:

1. User feedback
2. Accuracy and freshness
3. Depth and coverage
4. Pricing
5. Compliance with privacy laws

User feedback is my North Star.

If real people who’ve been using a tool for months or years don’t love it, that’s a bad sign. I’m not buying vendor hype; I want the truth from the trenches.

Accuracy and freshness matters the most.

Since I can’t throw thousands of dollars at testing (wish I could), I leaned on user reviews to measure how accurate the vendor is.

Plus I also checked how often vendors update their databases. Fresh data beats ancient relics every time, unless you like cold leads and dead ends.

Depth and coverage is basically what kind of data you get on your leads.

I checked what kind of data each provider offers.

1. Is it simple info like name, title, contact, and basic demographics?
2. Does it offer detailed firmographics, technographic data, intent signals?
3. Does it offer full coverage across countries, industries, and decision-makers?

Data samples and user feedback helped me sniff out the real players.

How affordable is it?

So many vendors treat pricing like it’s some secret government file. Hidden, confusing, or just plain weird.

I did some detective work and math to figure out the real cost per 1,000 rows so you can avoid getting swindled.

Compliance with data privacy laws like GDPR is a must.

Vendors who can’t prove they play by the rules didn’t make my list. Staying legal is boring but necessary because… better safe than sorry, babes.

So based on these factors, here goes my list.

Best B2B data providers and vendors of 2025

To keep things clear for you, I split this list into two parts:

1. Top 10 B2B data providers
2. Other B2B data providers

The top 10 are the vendors I rated highest based on my testing. They offer the best mix of accuracy, coverage, pricing, user feedback, and compliance.

Other B2B data providers are vendors that didn’t make my top 10. Either because they missed a few criteria or scored a bit lower.

But I didn’t want to leave them out because they have unique features or work well for specific needs.

This way, I give you the best overall picks plus some solid options that might fit your situation better.

Let’s start with the top 10.

Top 10 B2B data providers

1. Lobstr.io

Avg rating (G2+Capterra): 5

Features

1. Real-time data with contacts included
2. Access to dozens of sources
3. Built-in email validation
4. Export to CSV, Google Sheets and S3
5. API for automated data collection

What does Lobstr.io actually do?

It’s a web scraping tool that lets you collect all the fresh and juicy details about leads directly from the source platforms like LinkedIn.

You can collect everything available on a lead’s profile and enrich it further with verified emails.

Lobstr.io can also mine local business data from platforms like Google Maps.

You can pull every detail from the listing, their social media pages, and even get all verified emails of those businesses.

Lobstr.io supports a variety of verticals including local businesses, social media handles (Facebook, Twitter), LinkedIn, e-commerce, real estate, and more.

You can use it to build your own B2B database with as much info as you want.

If you need even fresher data, Lobstr’s scheduling feature automates data collection so you’re always getting fresh data without lifting a finger.

Shortcomings

Lobstr.io isn’t a pre-built database.

It won’t spit out 100k rows instantly when you type your query. Instead, you choose the platform, give it the input, and it scrapes the data in real time.

Depending on your request size, this can take minutes or even hours.

Also, it doesn’t offer direct CRM integrations. You’ll have to connect via Google Sheets or use their API to sync data with your CRM.

Pricing

1. Starts at $57/month
2. $13 per 1,000 rows (with fully verified emails)

2. Clay

Avg rating (G2+Capterra): 4.9

Features

1. One-click access to 100+ data sources
2. Waterfall enrichment
3. Lead scoring and TAM sourcing
4. Custom signals and alerts
5. Native push to CRMs and email tools
6. Workflow automation for outreach

Clay is super accurate and it's the main reason this tool is on top in my list. It’s built for power users who want massive data coverage and real-time enrichment all in one place.

But there’s a steep learning curve and many users have reported bugs in CRM connectors

So it isn't a super smooth platform but full marks for accuracy, depth, and coverage.

I have already written an in-depth review of Clay before, do check it out for a full overview.

It offers custom API integrations, so you can sync it to Lobstr.io and literally do B2B data collection on steroids.

This combo is perfect for building the most clean, updated, and accurate B2B leads database.

Pricing

1. Starts at $149/month
2. $140 per 1,000 rows

3. Cognism

Avg rating (G2+Capterra): 4.6

Features

1. 170+ million contacts in the database
2. Phone-verified mobile numbers
3. Complete lead data with intent signals
4. Advanced prospecting filters
5. AI-powered lead suggestions
6. Smooth integration with popular CRMs

Cognism’s biggest selling points are its ease of use and huge contact database. Plus, its CRM integrations are slick.

The shortcomings?

Data accuracy, especially phone numbers, is a big concern for users.

Though most of the users are satisfied with data accuracy, still around 10 to 15% of G2 and capterra reviews complain about data inaccuracy and outdated phone numbers.

Pricing

1. $1,500 to $10,000 per year
2. Price per 1,000 contacts can be from $150 to $2,000

4. Apollo.io

Avg rating (G2+Capterra): 4.6

Apollo is a sales intelligence and engagement platform with a huge database and tools to enrich your data.

Features

1. Lead database with 200M+ contacts
2. 60+ data filters and waterfall enrichment
3. Workflow engine to automate tasks
4. Conversation intelligence to analyze calls and messages
5. Direct integrations with popular outreach tools and CRMs
6. Automated outreach features

Apollo is easy to use and works well with popular CRMs like Hubspot and SalesForce. It has a strong database.

But like many tools, some users report outdated data occasionally. These complaints are limited, but worth mentioning for honesty’s sake.

It’s good for finding US region B2B data, but has limited EU data.

I have covered Apollo in detail in this article:

Pricing

1. Starts at $58 per month
2. $100 per 1,000 rows

5. UpLead

Avg rating (G2+Capterra): 4.6

UpLead is a B2B lead intelligence platform with a global database of verified business contacts, including emails and phone numbers.

Features

1. 160 million contacts
2. Advanced lead search with 50+ filters
3. Technographics and intent data included
4. Integrates with popular CRMs
5. Real-time email enrichment and validation

UpLead is easy to use and offers similar filters to Apollo and Cognism. It offers high-quality data and is generally accurate.

But it has less info on smaller companies under $5 million in revenue. Some users also mention missing data points.

Pricing

1. Starts at $99 per month
2. $500 per 1,000 rows of contacts data

6. Lead411

Avg rating (G2+Capterra): 4.6

Lead411 is a B2B sales lead database you can use through a web interface or Chrome extension. It offers a large contact list and tools to help you find and score leads.

Features

1. 450 million contacts
2. Data re-verified every 90 days
3. Integrates with 25+ CRM and sales tools
4. Includes intent data and lead scoring
5. Allows users to submit data
6. Real-time email validation

Many users say Lead411 has limited search features. It lacks advanced geo filters and detailed search options like competitor tools.

Plus the website is often slow, and I personally felt that the user interface looks old and cluttered.

Pricing

1. Starts at $99 per month
2. Costs about $400 per 1,000 rows

7. LinkedIn Sales Navigator

Avg rating (G2+Capterra): 4.5

LinkedIn Sales Navigator is a premium subscription made for sales teams to find, track, and connect with leads and companies on LinkedIn.

Features

1. Access to 1.1 billion LinkedIn profiles
2. Advanced lead and account search
3. Lead and account tracking
4. Relationship maps and org charts
5. Outreach through LinkedIn InMail
6. Basic buyer intent signals

It's not a traditional B2B data vendor, so you can't download leads from it directly. The enterprise plan does support CRM export though.

I have explained all about Sales Navigator in this dedicated article:

To get the most out of Sales Navigator, you'll need tools like Lobstr.io's Sales Navigator Leads Scraper.

Lobstr.io automatically collects all lead data from Sales Navigator search, enriches them with verified emails, and exports them to Google Sheets.

Here's a detailed guide on how to do it:

Pricing

1. Starts at $99 per month
2. $112 per 1,000 leads (when used with Lobstr.io)

8. 6Sense

Avg rating (G2+Capterra): 4.5

6Sense is a revenue intelligence platform that uses AI and intent data to help sales and marketing teams find and prioritize high-value accounts.

Features

1. 450 million B2B profiles
2. Data refreshed every 45–60 days
3. Company and people search
4. Intent data and predictive AI insights
5. AI-powered sales intelligence tools
6. CRM and sales engagement platform integrations

It's the best option if you're looking for up to date B2B data. The data refresh frequency is better than all tools in the list.

Another plus point of 6Sense is its high-quality intent data and AI powered insights.

The biggest downside of 6Sense is its steep learning curve. It's too complicated. Your sales team or yourself will need some training to use it properly.

Pricing

1. Rumored starting pricing is $60k per year (offers custom pricing only)
2. $1,000 per 1,000 rows of data (speculative)

9. Adapt

Avg rating (G2+Capterra): 4.5

Features

1. 250 million profiles
2. Covers over 3,000 industries and sectors
3. 50+ data attributes
4. CRM and API integrations
5. Lead intelligence OS

If you want a coverage-heavy B2B data provider, Adapt.io is a solid choice. Just don’t expect much depth or advanced signals.

I’ve already done a detailed review of Adapt.io in a previous article if you want to dive deeper.

Pricing

1. Starts at $49 per month
2. $100 per 1,000 rows of data

10. Coresignal

Avg rating (Datarade): 4.8

Coresignal offers access to a large B2B data set. It’s not usually on popular listicles, but it gets a lot of love on social media.

Features

1. 70M+ company profiles
2. Data updated every 30 days
3. 80+ datapoints
4. Offers firmographic, technographic, and funding data

I couldn’t find reviews on sites like G2 or Capterra, so I tested Coresignal myself and also checked user feedback from social media like Reddit, X, and LinkedIn.

The API works well, but the user interface? Not so much.

It’s buggy, slow, and clunky. Coverage is generally good across countries, but users report missing industries and sectors.

Pricing

1. Starts at $49 per month
2. $30 per 1,000 rows

Now let’s have a quick look at B2B data providers that do deserve a mention but couldn’t make it to the top 10 list.

9 other B2B data providers worth trying

11. Spherescout.io

It pulls info from local business listings like Google Maps and Yelp, adding verified emails, phone numbers, websites, and social media contacts.

Best for: Finding contact information on smaller, local businesses.

Buyer intent signals and tech stack data come with higher-tier plans.

Why not in top 10: A lot of accuracy issues and poor data quality kept it off the top list.

It offers 50 million profiles, an AI auto-list builder, intent signals, and outreach features.

Why not in top 10: Limited coverage outside North America, poor data quality, and not very scalable.

18. Datanyze

19. Techsalerator

Why not in top 10: No reviews on major sites like G2 or Capterra, poor customer support reported elsewhere, and complaints about outdated or irrelevant data.

And that’s my list!
